Chickpea Characterization
The characterization of germplasm is essential for its effective use in crop improvement. Phenotypic characterization involves recording traits that are highly heritable, easily observable, and consistently expressed across different environments. The ICRISAT germplasm accessions are characterized at the Patancheru location in India (Latitude: 17.51° N, Longitude: 78.27° E, Altitude: 545 m). The descriptors developed for characterization and preliminary evaluation are followed for each crop assessed. Detailed crop-specific characterization information can be found in the ICRISAT Genebank Technical Manual manual.
